What Acira is

  • A browser built on Chromium. It shows websites with the same engine as Chrome and Edge, and you can add extensions from the Chrome Web Store (see Extensions for what works).
  • Private from the first page. Ads, trackers and third-party cookies are blocked from the start. See Ads and trackers.
  • No account. You do not sign in to Acira. There is no sync, so your bookmarks and history do not leave your computer.
  • Purely a browser. Acira has no AI assistant and no AI features right now. An optional AI-free mode hides AI answers and AI buttons on websites you visit. See AI-free mode.
  • Four kinds of private browsing. A private tab, a private window, a Tor tab and a Tor window. See Private tabs and windows and Tor.
  • Room to organize. Tabs along the top or in a sidebar, tab groups, split view, workspaces and link previews.

What Acira does not do

  • It does not provide a VPN. It can control a VPN app you already have. See DNS, proxy and VPN.
  • It does not make you invisible online. A Tor tab hides your IP address from sites. It does not hide your browser fingerprint.
  • It does not sync between devices.
  • It runs on Windows, Mac and Linux (x86_64). There is no phone version.

See Install Acira. Where a feature works differently on a Mac, the page says so. In general, use Cmd where these pages say Ctrl.

How these pages are written

Each page says what a feature is, how to turn it on or use it, what you can change with the default of each setting, and what its limits are. Names of buttons, menus and settings are written the way they appear on screen. A setting path such as Settings › Privacy › Private browsing means: open Settings, choose Privacy, then find Private browsing.

Open Settings from the Acira menu, or press Ctrl+,.
